A Korean Hagwon is a private educational institution in South Korea that offers supplementary classes to students. These schools focus on various subjects, including English, math, and science, and are popular among parents seeking to enhance their children's academic performance. Hagwons operate outside the regular school hours, often in the evenings or on weekends. Hagwons can vary in size and specialization, ranging from small tutoring centers to large academies. They play a significant role in the competitive South Korean education system, where students often attend multiple hagwons to prepare for college entrance exams and improve their chances of academic success.
